How is BCG given?
BCG is injected directly into the bladder using a catheter inserted into the urethra (the tube for passing urine out of your bladder). You will receive this medicine in a clinic or hospital setting.
BCG is usually given once every week for 6 weeks, and then given every 3 to 6 months for up to 2 years. Follow your doctor's instructions about your specific dosing schedule.
You will need hold the medicine in your bladder as long as possible up to 2 hours. During that time you may be encouraged to lie down or stay relaxed.
For at least 6 hours after you are treated with BCG, your urine will still contain some of the medication and the bacteria it is made from. To prevent the spread of this bacteria, use a toilet rather than a urinal, and sit on the toilet while urinating.
Before you flush the toilet, disinfect the urine with household bleach in an amount that is approximately equal to how much you have urinated. Pour the bleach into the toilet in which you urinated, let it stand for 15 minutes and then flush.
Your doctor may ask you to drink extra fluids for several hours after your BCG treatment to help flush out your bladder. Follow all instructions.
Call your doctor right away if you have a fever after receiving BCG, especially if the fever lasts for several hours or longer.
This medicine can affect the results of certain medical tests. Tell any doctor who treats you that you are using BCG.
